Glow discharge plasma technique was firstly applied to treat amorphous Co–B catalyst. Both the amorphous Co–B particles before and after plasma treatment were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), inductively coupled plasma atomic emission spectroscopy (ICP-AES), X-ray photoelectron spectroscopy (XPS), N2 adsorption–desorption, and CO temperature-programmed desorption (TPD). After plasma treatment, relatively larger uniform spherical Co–B particles with mesopores have been formed and the synergistic effect between Co and B enhanced. Furthermore, the mesopores formed on the surface of Co–B after plasma treatment enabled it with higher specific surface area. During the liquid-phase cinnamaldehyde (CMA) hydrogenation, Co–B after plasma treatment exhibited higher CMA conversion and cinnamyl alcohol (CMO) selectivity.
